ELEVATED CARRIER.

Specification of Letters Patent.

Application filed April 27, 1905. Serial No. 257,622.

' such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to carriers, such as hay-forks and the like,traveling upon elevated guides, and more particularly to devices for usein connection therewith, and has for its object to provide a device bymeans of wh ch a carrier after discharging its load may be returned toposition to receive another load.

Another object is to provide a device of this nature which will beextremely simple in arrangement and construction and which may thus bemanufactured at a low figure and in which the parts will be unlikely tobecome deranged or broken.

Other objects and advantages will be apparent from the followingdescription, and it will be understood that changes in the specificconstruction shown and described may be made within the scope of theclaims and that any suitable materials may be used without departingfrom the spirit of the invention.

In the drawings forming a portion-of the specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a view showing a hay-fork with which the present inventionis con nected. Fig. 2 is a side elevation of a returning device. Fig. 3is a front elevation. Fig. 4 is a section on line 4 4 of Fig. 2. Fig. 5is a detail perspective view of the drum-supporting parts. Fig. 6 is anelevation of the drums.

Referring now to the drawings, the present invention comprises a bracket5, which is formed of a metallic bar bent at right angles to form avertical portion 6 and horizontal ortion 7, the former being boltedagainst the ace of a suitable support 8 Adiagonal brace 9 connects theportions 6 and 7, as shown. Attached to the portion 7 at its free endthere is a horizontal-exten ding metallic disk 1 0, having a circularseries of perforations 1 1 therein adjacent to its periphery. The plate10 has a central opening 12, which registers with an opening 13, formedin the portion 7 of the bracket 5, and these registering openingsreceive an upwardly-extending threaded pin 14, carried by the bight ofan inverted-U- shaped yoke 15. A nut 16 is engaged with the pin 14 abovethe bracket, and the yoke is rotatable with respect to the bracket. Theyoke is secured to the disk 10 by means of pins 17, engaged in the bightof the yoke and in the disk, and the disk is thus rotatable with theyoke.

Formed through the portion 7 of the bracket 5 there is an opening 18,which is disposed for successive registration with the openings of theseries 11 when the disk and yoke are rotated, and in the registeringperforations there may be engaged a pin 19 to hold the yoke and diskstationary.

Formed in the free ends of the legs of the yoke there are registeringhorizontal bearings 20, which receive a shaft 21, upon which there aremounted a larger and a smaller winding-drum 22 and 23, respectively.These drums include a wooden cylinder 24, which for substantially halfits length is turned down to considerably less than its original size,as shown at 25, to form the core for the smaller drum 23, while theunturned-down portion forms the core 26 for the larger drum 22. Ametallic disk 27 is secured against the outer face of the core 26 andprojects beyond the periphery of its core, as shown, and

a similar disk 28, having a central opening 29, which receives the coreof the smaller drum, is secured against the inner face of the core 26and projects beyond the periphery thereof. Asmaller disk 29is securedagainst the end of the core and projects beyond the periphery thereof,as shown. These two drums lie between the spaced legs of the yoke 15 andare rotatable with the shaft 21.

A metallic yoke 30 is secured at the ends of its spaced legs to the legsof the yoke 15 at points below the top of the core of the drum 22, andthis yoke 30 lieswith its bight 31 forwardly of the drum 22 and extendsat right angles to the yoke 15. The bight 31 has an opening 32 thereinprovided with a wooden bushing 33, in which there is engaged acarrier-returning rope 34, which is attached to the drum 22 and isadapted to be wound thereupon, the yoke 30 thus forming aguide for therope.

Secured to the lower ends of the spaced legs of the yoke 15 are the legs34 of a yoke 35, which extends downwardly and rearwardly from the yoke15 and lies with its bight 36 beyond the periphery of the drum 22, theportions of the legs 34 lying adjacent to the bight being bentdownwardly at an angle, as shown at 37, to bring the bight 36 intohorizontal position. The bight 36 has an opening 38 therein which isprovided with a wooden bushing 39, and this bushing receives a cable 40,which is secured at one end to the drum 23 and is adapted to be woundthereupon. The other end of the rope 40 is attached to the bight 36 ofthe yoke 35, and between this end and the bushing 39 the cable is passedthrough pulleys 41, carried by a weight 50, the action of this weightbeing to hold the cable 40 normally unwound from the drum 23. The cable40 and the rope 34 are wound upon their respective drums in oppositedirections, so that when the cable is unwound from the drum 23 the rope34 is wound upon the drum 22.

The rope 34 is attached to the carrier in connection with which thepresent invention is used in such a Way that when the carrier is movedwith its load into position to discharge the latter the rope 34 isunwound from the drum 22, this unwinding revolving the drum 23, as willbe readily understood, to wind the cable 40 thereupon. It will thus beapparent that when the carrier is released the weight will cause thecable 40 to unwind from the drum 23, winding the cable 34 upon the drum22 and returning the carrier to its original position.

The legs 34: of the yoke 35 extend u wardly and forwardly of the legs ofthe yo e 15 and are secured at their ends to the legs of the yoke 30,these yokes thus bracing each other against movement with respect to theyoke 15, and it will be seen that the yoke 15 and the portions carriedthereby may be revolved with respect to the bracket 5 to suit differentconditions, the yoke 15 being held at the different points of itsrotations by the pin 19. It is thus possible to move the drums to extendat difierent angles to the bracket, so that if it be necessary to securethe bracket to a support in such a position that the rope 34 does notlie in a plane with the bracket the drums may be shifted to bring theminto the plane of the rope, thus insuring efiicient operation of thedevice.

The cylinder 24 is composed of a plurality of segmental blocks a, asshown in Fig. 6, which are tightly secured together.

What is claimed is 1. A device of the class described comprising abracket a yoke connected with the bracket andincluding spaced legs,drums revolubly mounted between said legs and arranged for simultaneousrotation, cables engaged with the drums and adapted to be woundthereupon in opposite directions, a weight connected with one of thecables and arranged to hold the latter unwound from its drum and guidesfor the ropes said guides being secured to the yoke and to each other tobrace each other against movement with respect to the yoke.

2. A device of the class described comprisin a yoke, drums revolublymounted in the yore, cables engaged with the drums and guides for thecables said guides being secured to the yoke and to each other to braceeach other against movement with respect to the yoke.

3. A device of the class described comprising a bracket, drums connectedwith the bracket for rotation in a vertical plane,cables engaged withthe drums and adapted to be wound thereupon or unwound therefrom whenthe drums are rotated, said drums being also shiftable pivotally in ahorizontal plane with respect to the bracket and means for holding thedrums at different points of their horizontal pivotal movement.

In testimony whereof I afhx my signature in presence of two witnesses.
